Mots clés
~~~~~~~
Parole spontanée, son, bruit, audio, reconnaissance, transcription, apprentissage.

Contexte de l’étude
~~~~~~~~~~~~~~~
Lors d’un vol, tous les paramètres sont enregistrés dans deux calculateurs distincts, le DFDR (Digital Flight Data Recorder) et le CVR (Cockpit Voice Recorder). Le DFDR enregistre les paramètres techniques du vol. Le CVR enregistre toutes les conversations entre l’équipage, le personnel de cabine, les centres au sol (navigation aérienne, compagnie…). Sont également enregistrés toutes les alarmes qui peuvent survenir à bord ainsi que tous les bruits qui peuvent être entendus dans le poste de pilotage.

Intérêt de l’étude
~~~~~~~~~~~~~
Au sein du département avionique, le contenu du CVR, suite à un vol d’essais et plus particulièrement ceux liés à une certification, est analysé afin de corréler tous les évènements tracés par les pilotes et ingénieurs navigants avec le contenu de l’enregistrement. Cette analyse a aussi pour but d’identifier et de caractériser tous les évènements sonores imprévus. L’analyse et la transcription sont faites par une simple écoute.
Afin d’améliorer la fiabilité, la pertinence, l’exhaustivité et la répétitivité des analyses effectuées, l’intérêt de l’étude est de proposer des algorithmes capables d’extraire du bruit ambiant du poste de pilotage, de la voix, des sons synthétiques et des bruits caractéristiques afin de les transcrire automatiquement.

Principaux objectifs de l’étude
~~~~~~~~~~~~~~~~~~~~~~~~
Ce stage adresse à la fois des problématiques liées à la reconnaissance de sons prédéfinis (existence d’une référence audio), la détection de bruits spécifiques et la transcription de la parole spontanée.
Ce sujet de stage est lié à une thèse qui sera financée avec un financement CIFRE avec AIRBUS. La thèse est divisée en 3 parties correspondant à l’étude de chacune des trois catégories de sons explorées ; les approches seront de fait différentes :
1. Pour la reconnaissance des sons (alarmes, code morse…), il est possible de définir des prototypes ou références. C’est pourquoi l’étude s’orientera vers l’emploi d’une part d’algorithmes de détection de fréquences caractéristiques en prenant en compte les contraintes d’un environnement hétérogène (bruit, recouvrement…) et d’autre part de méthodes de reconnaissance des formes classiques appliqués à l’audio tels que ceux employés en reconnaissance de motifs sonores [13].
2. La détection des bruits représentatifs (régime moteur, train d’atterrissage…) ou inattendus (usure anormale, parasite…), passera par une analyse des signatures
acoustiques caractéristiques pour en déduire une modélisation. Cette détection nécessitera une phase d’apprentissage.
Pour ces deux premières parties, le titulaire s’appuiera sur les résultats d’un stage de fin de cycle d’ingénieur pour lequel un prototype a déjà été développé. Il s’agira
d’enrichir la démarche scientifique, puis de compléter et de confirmer les choix techniques qui ont été proposés.
3. La reconnaissance de la parole qui est de loin la plus importante, s’orientera d’abord vers une étude de faisabilité. Les deux principales difficultés sont liées à la production même de la parole qui est quasi « spontanée » et à l’environnement dans lequel la prise de son est faite.
Dans un premier temps, le titulaire devra effectuer une analyse très précise de l’environnement, bien plus contraignant que les environnements « conventionnels »
dans lesquels sont développés la majorité des systèmes de reconnaissance de la parole (parole téléphonique, journaux d'information en anglais [1], français [2],
sessions du parlement européen [3]). Il existe des études sur l'influence de la dégradation due aux environnements bruités : dans le secteur de la construction [4],
dans le secteur aéronautique [5]. Les travaux dans ce dernier secteur ont principalement pour objectif depuis les années 1980 de réaliser une simple
commande vocale dans les cockpits. L'analyse de la parole à partir d'enregistrements CVR n’a jamais fait l'objet d'étude, seules des recherches sur les sons d'alerte ont été menées [6,7].
Dans un second temps et une fois l’analyse effectuée, le titulaire s’attachera à définir les spécifications du système de reconnaissance automatique, tout en respectant les contraintes suivantes :
- Contraintes liées à un environnement fortement bruité et altéré par des événements sonores liés à l’exploitation de l’avion (recouvrement).
- Contraintes liées à une population multiculturelle : langue (capacité à changer de langue pour un même locuteur), accent, vocabulaire.
- Contraintes liées aux conditions dans lesquelles le locuteur opère : augmentation du débit, stress, fatigue.
Les principales pistes de recherche envisagées se déclinent selon deux axes :
- La compensation au niveau de la paramétrisation : une première analyse des différents bruits des enregistrements CVR permettra de cibler les traitements pour lutter contre le bruit existant (soustraction cepstrale, normalisation de la variance, filtrage ARMA, filtres RASTA...). Un deuxième axe consiste à s’appuyer sur des résultats récents en compensation de bruit dans le domaine cepstral, domaine de paramétrisation le plus performant en reconnaissance de parole. Il s’agit de décomposer l’espace de représentation en une composante utile pour la reconnaissance et une composante dite de nuisance qui rend compte de la variabilité de la session d’enregistrement [14]. Dans le cas présent et le cadre particulier des cockpits, cette variabilité représenterait l’environnement bruité, mais elle pourrait aussi rendre compte des conditions de stress du locuteur.
- L’adaptation au niveau des modèles acoustiques et linguistiques : les modélisations de la parole devront être adaptées aux différentes formes de parole présentes dans les enregistrements. Il s’agira de regarder plus précisément les vocabulaires employés pour les enrichir éventuellement, et tenir compte de la spontanéité au travers des modèles de langage (le traitement de la spontanéité reste à ce jour un défi très important à relever). Les techniques d'adaptation des lois des modèles acoustiques par Maximum Likelihood Linear Regression (MLLR) [8] et Maximum A Posteriori (MAP) [9] et les techniques d’adaptation au niveau de la modélisation elle-même (analyse factorielle appliquée aux modèles de Markov cachés [10,11]) seront les points de départs. Les adaptations des lexiques et des modèles de langage devront être étendues à ce type de dialogues [12].
Durant le stage, les parties 1 et 2 devront donner lieu à un prototype utilisable. La partie 3 pourra être concrétisé par la mise en place d’un système de reconnaissance de la parole de base.

Post Title:

Ph.D. Researcher in Speech Synthesis

Post Status:

3 years

Department/Faculty:

Centre for Language and Communication Studies (CLCS)

Location:

Phonetics and Speech Laboratory

Salary:

€16,000 per annum (plus fees paid)

Closing Date:

31st January 2013

Post Summary

A Ph.D. Researcher is required to work in the area of speech synthesis at the Phonetics and

Speech Laboratory, School of Linguistic, Speech and Communication Sciences. The position

will involve carrying out research on the topic of Hidden Markov Model (HMM)-based speech

synthesis. Specifically, we are looking for a researcher to work on developing a source-filter

based acoustic modelling for HMM-based speech synthesis which is closely related to the

human speech production process and which can facilitate modification of voice source and

vocal tract filter components at synthesis time.

Background to the Post

Much of the research carried out to date in the Phonetics and Speech Laboratory has been

concerned with the role of the voice source in speech. This research involves the development of accurate voice source processing both as a window on human speech production and for exploitation in voice-sensitive technology, particularly synthesis. The laboratory team is interdisciplinary and includes engineers, linguists, phoneticians and technologists.

This post will the main be funded by the on-going Abair project which has developed the first

speech synthesisers for Irish (www..abair.ie), and the researcher will exploit the current Abair

synthesis platform. In this project the aim is to deliver multi-dialect synthesis with multiple

personages and voices that can be made appropriate to different contexts of use. The post will also be linked to the FastNet project which aims at voice-sensitive speech technologies.

A specific goal of our laboratory team is to leverage our expertise on the voice by improving the naturalness of parametric speech synthesis, as well as making more flexible synthesis platforms which can allow modifications of voice characteristics (e.g., for creating different personalities/characters, different forms of expression etc).

Standard duties of the Post

Initially the researcher will be required to attend some lectures as part of the Masters

programme on Speech and Language Processing. This and a supervised reading

programme will provide a background in the area of voice production, analysis and

synthesis.

* In the very early stages the researcher will be required to develop synthetic voices, using

the Irish corpora, with the standard HMM-based synthesis platform (i.e. HTS). Note that

to work with the Irish corpora does not require a background in the Irish language, as

there will be collaboration with experts in this field.

* The researcher will be required to familiarise themselves with existing speech synthesis

platforms which provide explicit modelling of the voice source (e.g., Cabral et al. 2011,

Raitio et al. 2011, Anumanchipalli et al. 2010).

* The researcher will then need to first implement similar versions of these systems and

then work towards developing novel vocoding methods which would allow full parametric

flexibility of both voice source and vocal tract filter components at synthesis time.

Person Specification

Qualifications

* Bachelors degree in Electrical Engineering, Computer Science with specialisation in

speech signal processing, or related areas.

* Knowledge & Experience (Essential & Desirable)

* Strong digital signal processing skills (Essential)

*Good knowledge of HTS including previous experience developing synthetic voices

(Essential)

* Knowledge of speech production and perception (Desirable)

* Experience in speech recognition (Desirable)

Skills & Competencies

* Good knowledge of written and spoken English.

Benefits

* Opportunity to work with a world-class inter-disciplinary speech research group.

To apply, please email a brief cover letter and CV, including the names and addresses of two

academic referees, to: kanejo@tcd.ie and to cegobl@tcd.ie

-- Research Associate in Robust Speech Recognition
===============================================

The University of Sheffield, Department of Computer Science invite applications for a position as Research Associate to work on a project to research and develop robust technology for recognition of speech in meetings.  The associated project, DocuMeet, is funded by the European Union and involves collaboration with partners from academia and industry across Europe. The Speech and Hearing Research Group is responsible for speech technology in the project, but also contributes to some natural language understanding tasks.

Speech transcription of meeting data is a well-established task, with international competitions (held by U.S. NIST), and supported by several large-scale research projects. While significant progress has been made, the performance of recognition, detection and analysis systems is still very far from usable in many realistic, natural scenarios. There are many significant challenges seeking a solution: the acoustic complexity of meetings goes well beyond standard settings.: Noise and reverberation are standard; speech signals show significant amounts of overlap between speakers; varying degrees of emotion are present; and speakers are moving. All of these pose significant challenges to speech research and practical applications.

In the DocuMeet project we specifically work on speech recognition robustness to noise and reverberation. We aim to work on new algorithms that allow to factor environment and context in novel ways (e.g. eigen-environments).  The recordings from multiple microphones can be used to remove unwanted acoustics, while knowledge about a specific environment type should be used to adjust acoustic models of the recognition systems. Further we will investigate how such algorithms can be integrated with personalisation (acoustic/language) and how metadata can be used to inform such processes. Extensive experimentation of existing and new corpora will be required to demonstrate the effectiveness of the new techniques.

Applicants are required to have a track record of work on speech technologies including speech recognition, and to have had exposure to modern machine learning techniques. Ideally, such a track record is demonstrated by publications in international journals and conferences. The successful candidate will be required to hold a PhD in the field; work on the project will require publication of results, travelling to conferences and extensive visits to itslanguage offices. At this point the project duration is for one year, but extensions are likely.
The project will be embedded in the Speech and Hearing (SpandH) research group at (http://www.dcs.shef.ac.uk/spandh) in the Department of Computer Science, and in particular the subgroup on machine intelligence for natural interfaces (MINI). SpandH is amongst the largest speech research groups in the UK, with extensive infrastructure and a vibrant research environment. The group is well known internationally for its research, which reaches across traditional divides to encompass and link computational hearing, speech perception and speech technology. The MINI subgroup is led by Prof. Hain, currently has 13 members, and is amongst other things well known for speech recognition and classification. It has had systems with best performance in international competitions that are available to the public at www.webasr.org. The subgroup is currently involved in many projects, including an EPSRC programme grant (with Univ. of Cambridge, Univ. of Edinburgh), research organisations (e.g. Idiap, NICT), and Industry (e.g. Cisco, Google). It has its own extensive computing infrastructure, access to large quantities of data, as well as dedicated recording facilities.

The Department of Computer Science, which is a member of the Faculty of Engineering, was established in 1982 and has since attained an international reputation for its research and teaching. Currently there are over 100 members of staff in Computer Science, including 35 Academics. The Department has an international reputation for the quality of its research, and was awarded grade 5 in the 2001 research assessment exercise, and in the 2008 exercise, 65% of our research was rated world leading or internationally excellent in terms of its originality, significance and rigor.

Proposal for an INRIA PhD fellowship (Cordi-S)

Title of the proposal: Nonlinear speech analysis for differential diagnosis between Parkinson's disease and Multiple-System Atrophy

Project Team INRIA: GeoStat (http://geostat.bordeaux.inria.fr/)

Author of the proposal research subject: Khalid Daoudi (khalid.daoudi@inria.fr)

Keywords: speech processing, nonlinear speech analysis, machine learning, voice pathology,

dysphonia, dysarthria, Multiple-System Atrophy, Parkinson's disease.

Scientific context:

Parkinson's disease (PD) is the most common neurodegenerative disorder after Alzheimer's disease.

Prevalence is 1.5% of the population over age 65 and affects about 143,000 French. Given the aging of the population, the prevalence is likely to increase over the next decade.

Multiple-System Atrophy (MSA) is a rare and sporadic neurodegenerative adult disorder, of

progressive evolution and of unknown etiology. The MSA has a prevalence of 2 to 5/100 000 and has no effective treatment. It usually starts in the 6th decade and there is a slight male predominance. It takes 3 years on average from the first signs of the disease for a patient to require a walking aid, 4-6 years to be in a wheelchair and about 8 years to be bedridden.

The PD and MSA require different treatment and support. However, the differential diagnosis between PD and MSA is a very difficult task because, at the early stage of the diseases, patients look alike as long as signs, such as dysautonomia, are not more clearly installed for MSA patients. There is currently no valid clinical nor biological marker for clear distinction between the two diseases at an early stage.

Goal:

Voice and speech disorders in Parkinson's disease is a clinical marker that coincides with a motor

disability and the onset of cognitive impairment. Terminology commonly used to describe these

disorders is dysarthria [1].

Like PD patients, depending on areas of the brain that are damaged, people with AMS may also have speech disorders: difficulties of articulation, staccato rhythm, squeaky or muted voice. Dysarthria in AMS is more severe and early in the sense that it requires more early rehabilitation compared to PD.

Since dysarthria is an early symptom of both diseases, the purpose of this thesis is to use dysarthria,

through digital processing of voice recordings of patients as a mean for objective discrimination

between PD and MSA. The ultimate goal is to develop a numerical dysarthria measure, based on the

analysis of the speech signal of the patients, which allows objective discrimination between PD and

MSA and would thus complement the tools currently available to neurologists in the differential

diagnosis of the two diseases.

Project:

Pathological voices, such as in PD and MSA, generally present high non-linearity and turbulence.

Nonlinear/turbulent phenomena are not naturally suited to linear signal processing. The latter is

however ruling over current speech technology. Thus, from the methodological point of view, the goal of this thesis is to investigate the framework of nonlinear and turbulent systems, which is better suited to analyzing the range of nonlinear and turbulent phenomena observed in pathological voices in general [2], and in PD and MSA voices in particular. We will adopt an approach based on novel nonlinear speech analysis algorithms recently developed in the GeoStat team [3]. The goal being to extract relevant speech features to design new dysarthria measures that enable accurate discrimination between

PD and MSA voices. This will also require investigation of machine learning theory in order to develop robust classifiers (to discriminate between PD and MSA voices) and to make correspondence (regression) between speech measures and standard clinical rates.

The PhD candidate will actively participate, in coordination with neurologists from the Parkinson's

Center of Haut-Lévêque Hospital, to set up the experimental protocol and data collection. The latter

will consist in recording patient's voices using DIANA or EVA2 workstation (http://www.sqlab.fr/).

Offre de post-doc au LIUM
Traitement Automatique du Langage
–
Correction de sorties d’OCR, traduction automatique statistique, modélisation du langage.
Offre de postdoc au sein du laboratoire d’Informatique de l’Université du Maine (LIUM)  dans le domaine de la correction orthographique par méthodes de traduction automatique statistique.
Résumé de l’offre –  Thématiques : traitement du langage naturel, application à la correction d’OCR et traduction automatique statistique. –  Lieu : LIUM (Le Mans), équipe LST (http ://www-lium.univ-lemans.fr/). –  Période : disponible dès maintenant pour une durée d’un an renouvelable.
Contexte Ce postdoc s’inscrit dans le projet PACTE ('investissement d’avenir'), porté par l’entreprise Diadeis,  et dont sont également partenaires l’équipe Alpage (INRIA et Paris 7), et les entreprises A2ia et Isako.  PACTE a pour objectif l’amélioration de la qualité orthographique des textes issus de différentes méthodes de capture textuelle.  L’accent est mis sur les sorties d’OCR (reconnaissance optique de caractères) sur des textes imprimés scannés,  mais concerne également des données obtenues par reconnaissance d’écriture manuscrite, par saisie manuelle, et par rédaction directe.  Les techniques qui seront utilisées sont à la fois statistiques et hybrides, faisant usage d’outils et de ressources de linguistique computationnelle.
Objectifs Vérification et correction des sorties d’OCR par des méthodes de modélisation statistique du langage.  Les systèmes OCR utilisés n’exploitent pas ou peu de connaissance sur la langue.  L’objectif est d’exploiter la modélisation de la langue afin combler ce manque.
Utilisation de la traduction automatique statistique pour la correction d’erreurs des sorties d’OCR.  La correction des sorties d’OCR peut être vue comme une tâche de traduction d’un texte erroné vers un texte correct.  Dans le cadre de l’OCR, le paradigme de traduction doit être adapté afin de prendre en compte les spécificités de la tâche.
Le cadre applicatif de ce travail est assez exceptionnel, avec l’exploitation d’une grande quantité de données  issue notamment du Bureau Européen des Brevets (EPO - European Patent Office) et du Journal Officiel de l’Union Européenne.
Profil recherché – Compétences en informatique : environnement Linux, C++, scripting, etc. ; – Connaissances en apprentissage automatique, linguistique computationelle. – Une expérience en traduction automatique statistique est un plus. Le postdoc se déroulera au sein de l’équipe LST du LIUM.  Le LIUM est connu au niveau international pour ses recherches dans le domaine de la traduction automatique statistique,  et possède de nombreuses collaborations avec des universités et entreprises en Europe et aux États-Unis.
Contacts Envoyer une lettre de motivation et un CV montrant vos compétences pour ce poste aux adresses suivantes : Loïc Barrault : loic.barrault@lium.univ-lemans.fr  Holger Schwenk : holger.schwenk@lium.univ-lemans.fr

Postdoctoral position at LIMSI, France
Expressive Vocal Signal Analysis and Modelling

Content
During the post-production of a movie, as well as for video games, digital double rendering techniques are used to modify the actor’s performance without the need of playing the scene again. This project is aim toward characterising and reproducing the actor’s vocal personality. By creating a digital double of an actor, it will be possible to create new auditory scenes, as well as dubbing a movie – preserving the actor’s voice, habits and vocal personality.
We thus aim at characterising the expressive space of a given speaker, mainly in the prosodic domain, but also for its vocal quality and articulation peculiarities.
This postdoctoral position thus consist in implementing a set of voice analysis methods in order to observe the variations of vocal source and articulation in a given set of expressive performances. Databases presenting variations of vocal effort and expressive speech are already available and labelled. They will be analysed in order to model the expressive changes in tem of variation of the vocal signal. These models will be confronted to high-level descriptions of the expressive content of the databases.

Required competences
This research requires sound knowledge of signal processing applied to speech analysis. Skills in phonetic and/or linguistic are valuable.
Teamwork skills, and deadline oriented environment is mandatory.
Candidate with signal processing, computational linguistic or acoustic phonetic background will be taken into consideration.

Research team
This position is part of the French FUI ADN T-R project. It takes place at LIMSI-CNRS (www.limsi.fr) in the Audio & Acoustic group, in collaboration with partners from the industry.
LIMSI-CNRS is a research lab located in the University Paris-Sud campus, at Orsay, south of Paris. LIMSI is internationally renown for its works on speech processing. The Audio & Acoustic group focuses more specifically on speech analysis and synthesis, real-time audio processing and expressive sound.
This project will start as soon as possible (from may 2013), and is funded by the FUI agency for a maximum of 16 months. Gross monthly salary is approximately 2500€, on the basis of CNRS post-doctoral contract.

Supervision & contact:
This postdoctoral position will be supervised by Christophe d’Alessandro and Albert Rilliard.
Applications should be send to:

Marie Curie Research Fellow in Speech Synthesis and Speech Perception

'Using statistical parametric speech synthesis to investigate speech perception'

The Centre for Speech Technology Research (CSTR) 
University of Edinburgh

This is a rare opportunity to hold a prestigious individual fellowship in a world-leading research group at a top-ranked University, mentored by leading researchers in the field of speech technology. Marie Curie Experienced Research Fellowships are aimed at the most talented newly-qualified postdoctoral researchers, who have the potential to become leaders in their fields. This competitively salaried fellowship offers an outstanding young scientist the opportunity to kick-start his or her independent research career in speech technology, speech science or laboratory phonetics. 

This fellowship is part of the INSPIRE Network (http://www.inspire-itn.eu) and the project that the CSTR Fellow will spearhead involves developing statistical parametric speech synthesis into a toolbox that can be used to investigate issues in speech perception and understanding. There are excellent opportunities for collaborative working and joint publication with other members of the network, and generous funding for travel to visit partner sites, and to attend conferences and workshops.

The successful candidate should have a PhD (or be near completion) in computer science, engineering, linguistics, mathematics, or a related discipline. He or she should have strong programming skills and experience with statistical parametric speech synthesis, as well as an appropriate level of ability and experience in machine learning. The fellowship is fixed term for 12 month (to start as soon as possible). CSTR is a successful and well-funded group, and so there are excellent prospects for further employment after the completion of the fellowship.

The Marie Curie programme places no restrictions on nationality: applicants can be of any nationality and currently resident in any country worldwide, provided they meet the eligibility requirements set out in the full job description (available online - URL below).

An Open Position for Postdoctoral Research Associate in Speech Synthesis 

The Centre for Speech Technology Research (CSTR) 
University of Edinburgh

This post holder will contribute to our ongoing research in statistical parametric ('HMM-based') speech synthesis, working closely with Principal Investigators Dr. Junichi Yamagishi and Prof. Simon King, in addition to other CSTR researchers. The focus of this position will be to conduct research into methods for generating highly intelligible synthetic speech, for a variety of applications, in the context of three ongoing and intersecting projects in CSTR: 

The 'SALB' project concerns the generation of extremely fast, but highly intelligible, synthetic speech for blind children. This is a joint project with the Telecommunications Research Centre Vienna (FTW) in Austria, and is funded by the Austrian Federal Ministry of Science and Research. 

The 'Voice Bank' project concerns the building of synthetic speech using a very large set of recordings of amateur speakers (‘voice donors’) in order to produce personalised voices for people whose speech is disordered, due to Motor Neurone Disease. This is a joint project with the Euan MacDonald Centre for MND research, and is funded by the Medical Research Council. The main tasks will be to conduct research into automatic intelligibility assessment of disordered speech and to devise automatic methods for data selection from the large voice bank. 

The 'Simple4All' project is a large multi-site EU FP7 project led by CSTR which is developing methods for unsupervised and semi-supervised learning for speech synthesis, in order to create complete text-to-speech systems for any language or domain without relying on expensive linguistic resources, such as labelled data. The main tasks here will be to further the overall goals of the project, including contributing original research ideas. There is considerable flexibility in the research directions available within the Simple4All project and the potential for the post holder to form a network of international collaborators. 

The successful candidate should have a PhD (or be near completion) in computer science, engineering, linguistics, mathematics, or a related discipline. He or she should have strong programming skills and experience with statistical parametric speech synthesis. 

Whilst the advertised position is for 24 months (due to the particular projects that the post-holder will contribute to), CSTR is a stable, well-funded and successful group with a tradition of maintaining long-term support for ongoing lines of research and of building the careers of its research fellows. We expect to obtain further grant-funded research projects in the future. 

Informal enquiries about this position to either Dr. Junichi Yamagishi (jyamagis@inf.ed.ac.uk) or Prof. Simon King (Simon.King@ed.ac.uk).

**Projet
Le domaine du sentiment analysis et de l’opinion mining  est un domaine en plein
 essor avec l’arrivée en masse de données textuelles sur le web comportant des
 expressions d’opinions par les citoyens (critiques de films, débats sur les
 commentaires de forums, tweets) (El-Bèze et al. 2010)). Les recherches en
 traitement automatique des langues se mobilisent sur le développement de 
méthodes de détection d’opinion dans les textes en s’appuyant sur ces nouvelles
 ressources. La diversité des données et des applications industrielles faisant
 appel à ces méthodes multiplient les défis scientifiques à relever avec,
 notamment, la prise en compte des différents contextes d’énonciation (e.g.,
 contexte social et politique, personnalité du locuteur) et la définition du 
phénomène d’opinion à analyser en fonction du contexte applicatif. Ces méthodes
 d’analyse des sentiments dans les textes s’étendent également depuis peu à
 l’oral en passant par l’analyse des transcriptions automatiques issues de 
systèmes de reconnaissance automatique de la parole pour des problématiques 
d’indexation d’émissions radiophoniques ou de centres d’appels (Clavel et al.,
 2013), et peuvent être ainsi corrélées aux méthodes d’analyse
 acoustique/prosodique des émotions (Clavel et al., 2010).

Autre domaine scientifique en plein essor, celui des agents conversationnels
 animés (ACA) fait intervenir  des personnages virtuels intéragissant avec
 l’humain. Les ACA peuvent prendre un rôle d’assistant comme les agents
 conversationnels présents sur les sites de vente (Suignard, 2010), de tuteur 
dans le cadre des Serious Games (Chollet et al. 2012) ou encore de partenaire
 dans le cadre des jeux vidéos. Le défi scientifique majeur pour ce domaine est
 l’intégration, au sein de l’ACA, de la composante affective de l’interaction. 
Il s’agit d’une part de prendre en compte les comportements affectifs et des 
attitudes sociales de l’humain et d’autre part de les générer de façon
 pertinente.

Nous proposons pour cette thèse de travailler sur la détection des opinions et
 des sentiments dans un contexte d’interaction multimodale de l’humain avec un
 agent conversationnel animé, sujet jusqu'à maintenant peu étudié par la
 “communauté agent”. En effet, d’un côté, les ACA réagissent à des contenus
 émotionnels essentiellement non verbaux (Schröder et al., 2011) et de l’autre
 côté, les ACA “assistant” réagissent à partir des contenus verbaux informatif
 (Suignard, 2010) sans prendre en compte les opinions ou les sentiments exprimés
 par l’utilisateur. Des premières études ont été réalisées sur la reconnaissance
 de l’affect dans le langage dans un contexte d’interaction avec un agent 
 (Osherenko et al., 2009) mais celles-ci restent envisagées indépendamment de la
 stratégie de dialogue.

Les développements de la thèse s’intègreront dans la plateforme GRETA qui repose
 sur l’architecture SAIBA, une architecture globale unifiée développée par la 
“communauté agent” pour la génération de comportements multimodaux 
 (Niewiadomski et al., 2011). Greta permet de communiquer avec l’humain en
 générant chez l’agent une large palette de comportements expressifs verbaux et
 non verbaux (Bevacqua et al., 2012). Elle peut simultanément montrer des 
expressions faciales, des gestes, des regards et des mouvements de têtes. Cette 
plateforme a notamment été intégrée dans le cadre du projet SEMAINE avec le
 développement d’une architecture temps-réel d’interaction humain-agent 
(Schröder et al., 2011) qui inclut des analyses acoustiques et vidéos, un 
système de gestion du dialogue et, du côté de la synthèse, le système Text To
 Speech OpenMary et l’agent virtuel de la plateforme GRETA. A l’instar de ce 
projet, la détection d’opinions et de sentiments envisagée dans la thèse
 interviendra en entrée des modèles d’interactions multi-modaux de la
 plateforme. La stratégie de dialogue multimodale associée à ces entrées
 relatives au contenu verbal devra être définie et intégrée dans la plateforme
 GRETA.

**Enjeux
La thèse portera sur le développement conjoint de méthodes de détection des
 opinions et des sentiments et de stratégies de dialogue humain-agent. Les 
méthodes envisagées sont des méthodes hybrides mêlant apprentissage statistique
 et règles expertes.  Pour les stratégies de dialogue, le doctorant pourra
 s’appuyer sur les travaux réalisés dans le cadre du moteur de dialogue DISCO
 (Rich et al., 2012) et du moteur développé dans le projet Semaine(Schröder et
 al., 2011). Les méthodes développées pourront également s’appuyer sur des
 analyses de corpus humain-humain ou de type Magicien d’Oz (McKeown et al.,
 2012) et un protocole d’évaluation de ces méthodes devra être mis en place. En
 particulier, pour répondre à cet objectif, la thèse devra aborder les
 problématiques suivantes:
-  la définition des types d’opinions et de sentiments pertinents à considérer
 en entrée du moteur de dialogue. Il s’agira d’aller au-delà delà de la
 distinction classique entre opinions positives et opinions négatives, peu
 pertinente dans ce contexte, en s’appuyant sur les modèles issus de la
 psycholinguistique (Martin and White, 2007);
- l’identification des marqueurs lexicaux, syntaxiques, sémantiques et 
dialogiques des opinions et des sentiments;
 - la prise en compte du contexte d’énonciation: les règles implémentées
 pourront intégrer différentes fenêtres d’analyse : la phrase, le tour de parole
 et les tours de paroles antérieurs;
-  la prise en compte des problématiques temps-réel de l’interaction : des
 stratégies de dialogues seront définies en fonction des différentes fenêtres
 d’analyse afin de proposer des stratégies d’interactions à différents niveaux 
de réactivité. Par exemple, certains mots-clés pourront être utilisés comme
 déclencheurs de backchannel en temps réels et la planification des
 comportements de l’agent pourra être ajustée au fur et à mesure de l’avancement 
de l’interaction.

**Ouverture à l’international:
Ces travaux de thèse interviennent en complémentarité des travaux réalisés sur
 les interactions non verbales dans le cadre du projet européen FP7 TARDIS
 prenant comme application les Serious games dans le cas d’un entrainement à 
l’entretien d’embauche (http://tardis.lip6.fr/presentation) et des travaux
 réalisés sur le traitement des signaux sociaux dans le cadre du réseau
 d’excellence SSPNET (http://sspnet.eu/) Une collaboration avec Candy Sidner,
 professeur au département Computer Science du Worcester Polytechnic Institute 
et experte en modèles computationnels d’intéractions verbales et non verbales et
 à l’origine du moteur de dialogue DISCO (Richet et al. 2012) sera également
 mise en place.

Available PhD position with scholarship - Silent speech interface

GIPSA-lab, Grenoble, France

Incremental speech synthesis for a real-time silent speech interface

Context

: The design of a silent speech interface, i.e. a device allowing speech communication without the

necessity of vocalizing the sound, has recently received considerable attention from the speech research

community [1]. In the envisioned system, the speaker articulates normally but does not produce any audible

sound. Application areas are in the medical field, as an aid for larynx-cancer patients, and in the

telecommunication sector, in the form of a “silent telephone”, which could be used for confidential

communication, or in very noisy environments. In [2], we have shown that ultrasound and video imaging can be

efficiently combined to capture the articulatory movements during silent speech production; the ultrasound

transducer and the video camera are placed respectively beneath the chin and in front of the lips. At present, our

work focused mainly on the estimation of the target spectrum from the visual articulatory data (using artificial

neural network, Gaussian mixture regression and hidden Markov modeling). The other challenging issue

concerns the

estimation of acceptable prosodic patterns (i.e. the intonation of the synthetic voice) from silent

articulatory data only. To address this ill-posed problem, one solution consists of splitting the mapping process

into two consecutive steps: (1) a visual speech recognition step which estimates the most likely sequence of word

given the articulatory observations, and (2) a text-to-speech (TTS) synthesis step which generates the audio signal

from the decoded word sequence. In that case, the target prosodic pattern is derived from the linguistic structure

of the decoded sentence. The major drawback of this mapping method is that it cannot run in real-time. In fact, if

the visual speech recognition step can be done

online (i.e. words are decoded a short amount of time after they

have been pronounced), standard TTS systems need to know the entire sentence to estimate the target prosody.

This introduces a large delay between the (silent) articulation and the generation of the synthetic audio signal.

This delay prevents the communication partners from having a fluent conversation. The main goal of this PhD

project is to design a

real-time silent speech interface, in which the delay between the articulatory gesture and

the corresponding acoustic event has to be constant and as short as possible.

Goals:

The goal of this PhD project is twofold:

(1) Reducing the delay between the recognition

and the synthesis steps, by designing a new

generation of TTS system, called “

incremental

TTS system

” [3]. This system should be able to

synthesize the decoded words, with acceptable

prosody, as soon as they are provided by the

visual speech recognition system.

(2) Designing experimental paradigms in order to evaluate the system in realistic communication situations (faceto-

face, remote/telephone-like interaction, human-machine interaction). The goal is to study how a silent speaker

benefits from the acoustic feedback provided by the incremental TTS and how he/she adapts his/her own

articulation to maximize the efficiency of the communication.

ance'Offre de post-doctorat dans le cadre du projet ANR DIADEMS (Description, Indexation, Accès aux Documents Ethnomusicologiques et Sonores).

- Sujet de post-doctorat : identification / classification instrumentale

Durée : 12 mois

Salaire : environ 2000 €/mois

Date de début souhaitée : septembre 2013

La reconnaissance automatique d'instrument et la classification par famille d'instruments est un domaine de recherche actif du MIR (Music Information Retrieval) [Hei09] [Kit07] [Her06] [Ess06]. Les principales techniques reposent sur des méthodes statistiques utilisant des paramètres audio de type MFCC. Nous souhaitons ici tracer une voie nouvelle, permettant de faire le lien entre le traitement de la parole et le traitement de la musique, en considérant l'interprétation musicale comme une phrase, et l'instrument ou l'instrumentiste comme un locuteur.

Ce travail s'effectuera en parallèle d'une thèse en cours sur la caractérisation et l'identification de la voix chantée. Au cours de cette thèse, nous avons proposé une méthode permettant d'identifier les segments contenant de la voix chantée dans des enregistrements polyphoniques (e.g. musique 'pop'). L'objet actuel d'étude est de déterminer quels sont les paramètres du signal les plus pertinents pour caractériser différents styles de chant.

Une des pistes que nous souhaitons poursuivre sera d'identifier l'instrument en suivant le vibrato, de manière similaire à ce qui est proposé pour la voix chantée. En insistant sur la dimension temporelle plutôt que spectrale, nous pourrons aussi observer comment s'enchainent les respirations, les attaques sonores ou les changements timbraux utilisés par le musicien. Ce travail exploratoire nécessitera dans un premier temps d'effectuer des expérimentations sur des bases de données simples (telles que [Fri97] et [Got03]) afin de valider notre approche avant d'appliquer nos algorithmes aux données du projet DIADEMS.

Description du projet DIADEMS (Partenaires : LaBRI, IRIT, LESC, Parisson, LIMSI, MNHN, LAM-IJLRA)

Le Laboratoire d'Ethnologie et de Sociologie Comparative (LESC) comprenant le Centre de Recherche en Ethnomusicologie (CREM) et le centre d'Enseignement et de Recherche en Ethnologie Amérindienne (EREA) ainsi que le Laboratoire d'Eco-anthropologie du Muséum National d'Histoire Naturelle (MNHN) sont confrontés à la nécessité d'indexer les fonds sonores qu'ils gèrent et de faire un repérage des contenus, travail long, fastidieux et coûteux.

Lors de l'Ecole d'Été interdisciplinaire Sciences et Voix 2010 organisée par le CNRS, une convergence d'intérêts s'est dégagée entre les acousticiens, les ethnomusicologues et les informaticiens : il existe aujourd'hui des outils d'analyse avancés du son développés par les spécialistes en indexation qui permettent de faciliter le repérage, l'accès et l'indexation des contenus.

Le contexte du projet est l'indexation et l'amélioration de l'accès aux fonds d'archives sonores du LESC : le fonds du CREM et celui d'ethnolinguistique de l'EREA (« chanté-parlé » Maya, ainsi que celui du MNHN (musique traditionnelle africaine). Il s'inscrit dans la continuité d'une réflexion entreprise en 2007 pour l'accès aux données sonores de la Recherche : aucune application n'existant en « open source » sur le marché, le CREM-LESC, le LAM et la Phonothèque de la MMSH d'Aix-en Provence ont étudié la conception d'un outil innovant et collaboratif qui répond à des besoins « métier » liés à la temporalité du document, tout en étant adapté à des exigences du secteur de la recherche. Avec le soutien financier du Très Grand Equipement (TGE) ADONIS du CNRS et du Ministère de la Culture, la plateforme Telemeta développée par la société PARISSON a été mise en ligne en mai 2011 : http://archives.crem-cnrs.fr . Sur cette plateforme, des outils d'analyse élémentaires de traitement de signal sont d'ores et déjà disponibles.

Cependant, il est nécessaire de disposer d'un ensemble d'outils avancés et innovants pour une aide à l'indexation automatique ou semi-automatique de ces données sonores, issues d'enregistrements parfois longs, au contenu très hétérogène et d'une qualité variée. L'objectif du projet DIADEMS est de fournir certains des outils, de les intégrer dans Telemeta, en répondant aux besoins des usagers. Il s'en suit une complémentarité des objectifs scientifiques des différents partenaires : Les fournisseurs de technologies, l'IRIT, le LIMSI, le LaBRI et le LAM auront à :

- Fournir des technologies existantes telles que la détection de parole, de musique, la structuration en locuteurs. Ces outils visent à extraire des segments homogènes d'intérêt pour l'usager. Ces systèmes auront à faire face à la diversité des bases qu'il est proposé d'étudier dans ce projet ; leur hétérogénéité est liée aux conditions d'enregistrement, au genre et à la nature des documents, à leur origine géographique. Il faudra adapter ces systèmes dits « état de l'art » aux besoins des usagers.

- Proposer des outils innovants d'exploration du contenu de segments homogènes. Les travaux sur l'opposition voix parlée-déclamée-chantée, le chant, les tours de chant, la recherche de similarité musicale ne sont pas matures. Un véritable travail de recherche reste à faire et avoir à sa disposition des musicologues et des ethnomusicologues est un atout positif. Les ethnomusicologues, ethnolinguistes, acousticiens spécialistes de la voix et les documentalistes spécialisés vont jouer un rôle important dans le projet en tant que futurs utilisateurs des outils d'indexation : Les documentalistes doivent s'approprier les outils et apporter leur expérience afin d'adapter ces outils à leur besoin en indexation.

Un échange important doit se réaliser entre celui qui fournit l'outil, celui qui l'intègre et celui qui l'utilise. L'effort doit être porté sur la visualisation des résultats avec pour fin une aide forte à l'indexation en la rendant de fait semi-automatique Pour l'ethnomusicologue et le musicologue, l'objectif va au-delà de l'indexation. Il s'agit au travers d'aller et retour entre lui et les concepteurs de technologies de cibler les outils pertinents d'extraction d'information.

Reconnaissance du locuteur en milieu bruité

Nous avons atteint ces dernières années de très bonnes performances en reconnaissance du locuteur. Et ce, malgré la présence de la variabilité session. En effet, le variabilité session est prise en compte lors du scoring en utilisant une matrice de covariance modélisant cette dernière. Ce processus est effectué dans l'espace des i-vectors [1]. Le concept des i-vectors est devenu un standard en reconnaissance du locuteur.

Dans la dernière évaluation internationale NIST 2012, nous avons été confrontés à une nouvelle difficulté qui est le bruit additif [2], c'est à dire le bruit ambiant. La recherche pour réduire l'impact du bruit dans les systèmes de reconnaissance du locuteur est motivée en grande partie par le besoin d'appliquer les technologies de reconnaissance du locuteur sur des appareils portables ou sur l'Internet. Alors que les technologie promet un niveau supplémentaire de sécurité biométrique pour protéger l'utilisateur, la mise en œuvre pratique de ces systèmes doit faire face à de nombreux défis. Un des plus importants défis à surmonter est le bruit environnemental. En raison de la mobilité de ces systèmes, les sources de bruit peuvent être très variables dans le temps et potentiellement inconnus.

Nous proposons de travailler dans ce cadre : proposer des stratégies permettant de compenser l'effet du bruit additif, ces stratégies peuvent intervenir à différents niveaux du processus de reconnaissance: au niveau du signal, au niveau des modèles acoustiques, au niveau des i-vectors et au niveau du scoring....) .

• Débruitage des signaux

• Effet du bruit sur la VAD (Voice activity detection)

• Bruitage des modèles

• Intégration des caractéristiques statistiques du bruit dans la phase du scoring

Dans une deuxième partie du travail, nous proposons de nous mettre dans les meilleures conditions pour que le système soit le plus robuste au bruit. Par exemple, le choix de l'énoncé à prononcer par le locuteur peut avoir de l'influence sur les performances du système [3]. Faut a t-il avoir avoir le même énoncé pour tous les locuteurs, ou au contraire chaque locuteur se distingue des autres locuteur sur un ensemble bien précis d'unités acoustiques. Dans ce dernier cas, il faut trouver une stratégie, qui permet de déterminer l'ensemble des unités acoustiques qui différencient le plus possible un locuteur (des autres locuteurs). D'autres stratégies de robustesse au bruit doivent être proposées et étudiées dans le cadre de cette thèse. Une des pistes à explorer est l'utilisation de la théorie des caractéristiques manquantes (missing-feature theory), qui a été utilisée dans le domaine du traitement de la parole [4][5][6].

Les systèmes de reconnaissance du locuteur de l'état de l'art sont fondamentalement basés sur l'utilisation de l'UBM (Universal Backgroud Model), il s'agit d'un modèle trop simple pour le traitement et la modélisation de la parole. Dans le cas de la reconnaissance en milieu bruité, la tâche devient plus complexe, il est donc légitime de se reposer la question sur l'adéquation de ce modèle pour cette tâche. Nous proposons d'adapter une approche utilisant des HMM (ou autre modèle) à cette tâche tout en profitant des avancées récemment proposées ( Factor analysis, I-vectors, …).

Description scientifique

Si la définition de l'étendue de la variabilité en parole normale est une question fondamentale pour les théories

linguistiques actuelles, une façon d'aborder ses limites est d'essayer de déterminer ses frontières par le biais de la

variation pathologique. Comme le soulignent Duffy et Kent, 2001 « Science often takes advantages of nature’s

accidents to learn the principles of a process ». Sur ce principe, la connaissance de la parole pathologique s'appuyant sur

la compréhension des phénomènes d'altération « observables » dans la production de parole de patients atteints de

troubles de la parole devient une nécessité.

La parole dysarthrique correspond à une altération de la commande motrice d’origine centrale ou périphérique des

gestes de la parole. Des variations importantes existent dans la parole dysarthrique en relation avec un déficit de

l’exécution temporo-spatiale des mouvements de la parole et qui peuvent affecter différents niveaux de production

(respiratoire, laryngé et supralaryngé). La grande majorité des travaux ayant porté sur l'étude de la parole dysarthrique

repose sur des analyses perceptives. La raison principale tient dans le fait qu'un patient dysarthrique est dysarthrique

parce qu'il « s'entend/a l'air » dysarthrique. Les travaux les plus connus au niveau international sont ceux de Darley et

al., 1975. Ils ont conduit à l'élaboration d'une organisation des dysarthries en 6 classes (complétée par deux classes

supplémentaires par Duffy, 1995) sur la base de clusters physiopathologiques définis à partir de la concomitance de

caractéristiques les plus déviantes perçues par un jury d'écoute. L’hypothèse sous-jacente à la construction de ces

clusters est qu’un ensemble de paramètres perturbés simultanément, mis en relation avec l’atteinte neurologique,

reflèterait un processus physiopathologique particulier. Si cette classification reste d'actualité encore aujourd'hui pour

évaluer notamment la parole dysarthrique en pratique clinique, elle reste néanmoins sujette à controverses pour deux

raisons principales : la subjectivité des évaluations perceptives d'une manière générale et la difficulté pour un être

humain, même expérimenté, à distinguer et à juger perceptivement les multiples dimensions à prendre en compte dans

l'évaluation de la parole dysarthrique. En conséquence, différents travaux ont été menés à partir des années 80 à

aujourd'hui dans l'objectif de combiner ces analyses perceptives à des méthodes plus objectives et quantitatives telles

que les analyses instrumentales basées sur des mesures acoustiques ou physiologiques (revue de la littérature dans Kay,

2012). Si les analyses instrumentales peuvent s'appuyer sur des traitements semi- voire entièrement automatiques,

l'analyse acoustique fine nécessaire pour comprendre les phénomènes déviants inhérents à la dysarthrie dans le signal de

parole demeure encore très coûteuse en temps par un expert humain. Dans ce contexte, une grande part des études

présentes dans la littérature repose soit sur un nombre très restreint de patients ou sur une pathologie bien ciblée.

Pourtant, la grande variabilité des phénomènes déviants observés dans la parole dysarthrique en fonction de la

pathologie du patient, de l'avancement de la maladie ou de la sévérité de la dysarthrie requiert d'analyser une large

population de patients.

L'objectif de cette thèse est d'étudier comment les outils du traitement automatique de la parole pourraient permettre de

traiter de larges populations de patients dysarthriques et de focaliser l'attention des experts humains sur des zones de

déviance bien identifiées du signal en vue d'analyses plus fines. Ces travaux reposeront notamment sur le système de

transcription automatique du LIA et ses activités de recherche autour des mesures de qualité des transcriptions

(Lecouteux, 2008 et Senay, 2011). La granularité de la détection des zones de déviance – ici potentiellement le mot ou

la séquence de mots – sera dans un second temps affiner par des outils travaillant à des niveaux inférieurs allant

jusqu'au phonème (Fredouille, 2011).

Ces travaux devront tenter de répondre à différentes questions :

• Face à la variabilité des phénomènes de déviance observés dans la parole dysarthrique et répertoriés dans la

littérature, quels sont ceux qu'un système de détection automatique est capable de déceler ?

• Est ce qu'un système automatique est capable de mettre en évidence les mêmes phénomènes de déviance qu'un

expert humain lors d'une évaluation perceptive ?

• Les déviances détectées par le système automatique sont-elles pertinentes pour les phonéticiens ?

• Est-il possible de mettre en relation les déviances détectées avec la physiopathologie du patient (ex : indices

hypokinéthiques pour la maladie de Parkinson, indices paralytiques pour la SLA, …) ?

Les travaux autour du système de transcription automatique du LIA devraient également ouvrir des perspectives sur la

mise en place d'un système de mesures objectives de l'intelligibilité des patients dysarthriques.

Ces travaux de thèse seront réalisés dans le cadre d'une collaboration étroite entre le LIA (Corinne Fredouille) pour son

expertise autour des systèmes automatiques, le LPL (Christine Meunier et Alain Ghio) pour son expertise sur les

analyses acoustico-phonétiques et les évaluations perceptives, les hôpitaux de la Timone (Dr Danièle Robert) et des

Pays d'Aix (François Viallet) pour leur expertise clinique. Ils seront basés sur le corpus de patients dysarthriques

élaborés dans le cadre du projet ANR DesPhoAPady (2009-2012 – Fougeron, 2010). Ce corpus présente un large panel

de patients souffrant de différentes pathologies (maladie de Parkinson, Sclérose Latérale Amiotrophique, syndrôme

cérébelleux) et différents niveaux de sévérité de dysarthrie.

Scientific description

If the definition of the variability range in normal speech is a key issue for the current linguistic theories, a way of

dealing with its limits is to attempt to determine its frontiers through pathological variation. As reported by Duffy and

Kent, 2001 « Science often takes advantages of nature’s accidents to learn the principles of a process ». Based on this,

the knowledge of the pathological speech, based on the understanding of alteration phenomena, « observable » on the

speech production of patients suffering of speech disorders becomes a necessity.

Dysarthria is a group of speech disorders resulting from neurological impairments of speech motor control. Substantial

variations occur in dysarthric speech due to a deficit in the spatio-temporal execution of speech movements that affects

different levels of speech production (respiratory, laryngeal and supralaryngeal). The vast majority of research work

dedicated to the study of the dysarthric speech relies on perceptual analyses. The main reason is that a dysarthric patient

is dysarthric because he/she sounds dysarthric. The most known study, at international level, was done by Darley et al.,

1975. This work leads to organize dysarthria into 6 classes (completed with 2 additional classes by Duffy, 1995) on the

basis of physiopathological clusters defined from the co-occurrences of the most deviant features perceived by a

perceptual jury. The hypothesis underlying the building of these clusters is that a set of simultaneously disturbed

features, connected with the neurological injuries, should reflect a typical physiopathological process.

If this classification is still used nowadays to evaluate dysarthric speech in clinical practice notably, it remains

controversal for a couple of reasons : the subjectivity of perceptual evaluation and the difficulty for a Human being,

even with a high expertise, of distinguishing and assessing perceptually the multiple dimensions to take into account

when dealing with dysarthric speech. Consequently, different research work has been conducted since the 1980s until

now which aims at combining these perceptual analyses with more objective and quantitative approaches such as the

instrumental analyses based on acoustic or physiological measure (review of the literature can be found in Kay, 2012).

Contrary to the instrumental analyses which can rely on some semi- or full-automatic process, in-depth acoustic

analysis of speech necessary to understand the deviant phenomena related to dysarthria still remains very timeconsuming

for a Human expert. Based on this, a signifiant proportion of studies in the literature are conducted on a

limited number of patients or on a focused pathology. However, the large variability of deviant phenomena observed in

dysarthric speech according to the patient’s pathology, the stage of the disease, or the dysarthria severity require the

analysis of a large patient population.

The aim of this thesis is to study how the automatic speech processing tools could permit to treat large populations of

dysarthric patients and to focus Human experts’ attention on speech zones well identified as deviant for further in-depth

analyses. This work will rely on the automatic speech transcription developed at the LIA and its activities on the quality

measure of transcriptions (Lecouteux, 2008 et Senay, 2011). The granularity of the deviant zone detection – here the

word or set of words – will be refined, in a second step, by applying existing detection tools working at lower levels like

the phoneme (Fredouille, 2011).

This work will attempt to answer the following key issues :

• Given the variability of deviant phenomena observed on dysarthric speech and reported in literature, which

ones is an automatic detection system able to capture ?

• Is an automatic system able to highlight the same deviant phenomena as a Human expert will detect

perceptually ?

• Are deviant speech zones detected by an automatic system relevant for a phonetician ?

• Does a correlation between the type of deviant phenomena detected and the patient’s physiopathology

exist (e.g : hypokinetic feature for the Parkinson disease, paralytic features for ALS, …) ?

Studies relating to the automatic speech transcription should open up new perspectives on the implementation of an

objective system dedicated to the evaluation of the dysarthric patient’s intelligibility.

This thesis work will be carried out within a close collaboration between the LIA (Corinne Fredouille) for her expertise

on the automatic system dedicated to speech processing, the LPL (Christine Meunier and Alain Ghio) for their expertise

on acoustic-phonetic analyses and perceptual evaluations, both the hospitals of La Timone (Dr Danièle Robert) and desPays d’Aix (Pr. François Viallet) for their clinical expertise. It will be based on the dysarthric patient corpus designed

for the ANR DesPhoAPady project (2009-2012 – Fougeron, 2010). This corpus includes a large population of patients

suffering from various pathologies (Parkinson disease, ALS, cerebelar syndrom, …) and different levels of dysarthria

severity.

Le Département Parole et Cognition           du GIPSA-lab (www.gipsa-lab.inpg.fr/recherche/departement-parole-cognition.php)
        propose une bourse de doctorat financée par la région         Rhône-Alpes dans le cadre du programme ARC2 (http://www.arc2-q2v.rhonealpes.fr/)       sur le thème des troubles             du développement de la parole chez les enfants sourds             porteurs d’implants cochléaires : évaluation, diagnostic et             pistes pour la remédiation.   

Le
          financement est prévu pour une durée de 3 ans, et démarrera à           la rentrée universitaire 2013. Le (la) candidat(e) retenu(e)           sera affilié(e) à l’école doctorale LLSH de l’université           Stendhal de Grenoble (http://w3.u-grenoble3.fr/ecole_doctoraleLLSH/).

Compétences recherchées :

Ce
          sujet est proposé aux étudiant(e)s titulaires d’un Master 2 R,           issu(e)s d’une formation en sciences du langage ou           orthophonie, possédant une expérience en phonétique ou           psychologie expérimentales. Il est souhaitable, mais non           requis, d’être à l’aise avec le logiciel Matlab et les outils
          d’analyse du signal audio classiques (tels que Praat), ainsi que d’avoir           des compétences en statistiques. Les candidatures de           professionnels de santé en lien avec les troubles du langage           et/ou de l’audition (orthophonistes, audioprothésistes,           O.R.L., etc.) sont bienvenues. Les candidats devront avoir une           bonne maîtrise de la langue française (interaction avec des           enfants).

Encadrement :           Ce sujet sera co-dirigé par Anne Vilain du Département Parole           et Cognition du laboratoire GIPSA-lab et Michel Hoen de           l’équipe DYCOG (Dynamique Cérébrale et Cognition) du Centre de           recherche en Neurosciences de Lyon (U1028/UMR5292), en           collaboration avec le Laboratoire de Psychologie et           NeuroCognition de Grenoble.

 Les candidatures               (CV détaillé + lettre de motivation sont à envoyer à Anne.Vilain@gipsa-lab.grenoble-inp.fr)               avant le 25 juin 2013. Elles donneront lieu à une               pré-sélection avant entretien.

En
        2010, plus de 150 000 personnes dans le monde étaient équipées         d’un implant cochléaire, et la moitié d’entre elles étaient des         enfants. Pourtant, les difficultés en parole des enfants sourds         pré-linguaux porteurs d’implant cochléaire sont peu étudiées.         Les rares études disponibles révèlent l’existence de difficultés         de production et de perception de certains sons de parole, même         après plusieurs années d’usage. Or il a été montré que les         troubles de la parole peuvent induire des difficultés dans les         apprentissages scolaires, qui peuvent avoir un retentissement         affectif et social pour l'enfant. La rééducation orthophonique         ciblée des enfants porteurs d’implants cochléaires représente         donc un enjeu important en termes de qualité de vie à court et         long terme.

Le
        présent projet vise à (i) évaluer les difficultés de production         de parole persistantes chez un sujet sourd pré-lingual après         plusieurs années d’implantation cochléaire, et à (ii) mettre en         rapport ces difficultés avec les capacités des sujets à         percevoir les contrastes phonétiques, afin de (iii) proposer des         stratégies de rééducation adaptées permettant d’améliorer les         capacités phonologiques des enfants implantés.

Ces
        études porteront sur une population d’enfants implantés qui sera         comparée avec un groupe apparié d’enfants entendants. Le volet         « Production » s’appuiera sur l’enregistrement et l’analyse         acoustique de corpus de parole guidée et spontanée, et le volet         « Perception » sur des tests d’identification et de         discrimination de sons de parole.

Ce
        projet présente des enjeux théoriques et pratiques forts. Les         résultats pratiques permettront d’une part de diagnostiquer les         problèmes spécifiques persistant en production chez les enfants         implantés, afin de guider les pratiques de rééducation. Ils         permettront d’autre part de mieux décrire les étapes         chronologiques de la production et de la perception du langage         oral chez les enfants sourds porteurs d’implants, ce qui         fournira des repères cruciaux pour les thérapeutes.

Les
        apports théoriques de ce travail concernent la question du lien         entre production et perception de parole et la compréhension de         la construction d’un modèle interne pour la production de parole         au cours du développement. La seconde question théorique abordée         est la notion de période critique d’apprentissage et du rôle de         l’accès à des informations auditives pendant les premières         années de vie.

Mots-clés : handicap auditif - implant cochléaire – relations         perception / production en parole – trouble du développement du         langage – qualité de vie des enfants implantés

PhD positions - Computer Science, Natural Language Processing - Marseille, France

The NLP group of the Laboratoire d'Informatique Fondamentale of the Aix Marseille University has 2 open PhD positions in Computer Science in the context of an European project (3 years).

Location : Campus de Luminy (http://sciences.univ-amu.fr/sites-geographiques/site-luminy), Marseille, France
Starting : October 1st 2013
Deadline for application: July 15th 2013

The two fully funded PhD studentships will focus on 2 different aspects of the project:
1- Discourse parsing of speech.
This PhD will focus on developing discourse analysis methods adapted to a large range of conversational styles and domains from spoken conversations to social media interaction. Automatic methods will be studied for five types of discourse analysis: discourse parsing, event and temporal structure, argumentation structure and intra-document coreference. The applicative domain of this research will be the automatic summarization task of human-human dialogs. The language targeted will be French and English.

2- Syntactic and semantic parsing with deep learning methods.
Recently, neural network approaches based on a deep learning paradigm has been successfully applied to some NLP tasks such as POS and NE tagging or dependency parsing ( http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/de//pubs/archive/35671.pdf ). In this PhD we will investigate how this paradigm performs and can be adapted in the context of robust syntactic and semantic parsing of human human conversations collected on social media platforms and telephone call centres.

The successful candidates should :
- hold a relevant degree in the field of Natural Language Processing or Machine Learning.
- have good algorithmic and programming skills

Description of the lab:
The University of Aix-Marseille (AMU) is currently one of the largest university in France, created in 2012 from the fusion of the 3 former Aix-Marseille universities (Université de Provence, Université de la Méditerranée, Université Paul Cézanne).
The LIF (Fundamental Computer Science Lab), is a JRU between the Centre National de la Recherhe Scientifique (CNRS) and AMU. The Natural Language Processing group of LIF aims at developing symbolic and statistical methods for the automatic processing of textual and speech data. The two main characteristics of this research group are: (1) to host both linguists working on the development of rich linguistic resources such as syntactic and semantic lexicons and computer scientists with a very strong experience in numerical approaches for NLP; and (2) to work on both spoken and written languages, at the descriptive level as well as the application level thanks to a strong expertise of some members of the group in Automatic Speech Recognition methods.

INRIA Nancy Grand-Est (Nancy, France) - Speech Group, LORIA

Postdoctoral position

Accurate 3D Lip modeling and control in the context of animating a 3D talking head

Scientific Context

The lips play a significant role in audiovisual human communication. Several studies showed the

important contribution of the lips to the intelligibility of visual speech (Sumby & Pollack, 1954; Cohen

& Massaro 1990). In fact, it has been shown that human lips alone carry more than half the visual

information provided by the face (Benoît,1996). Since the beginning of the development of 3D virtual

talking heads, researchers showed interest to model lips (Guiard-Marigny et al., 1996, Reveret &

Benoît, 1998), as the lips increase intelligibility of the visual message. The existing models are still

considered as pure parametric and numerical models and do not take into account the dynamic

characteristic of speech. As audiovisual speech is highly dynamics, we consider that modeling this

aspect is crucial to provide a lip model that is accurately animated, and reflects the real articulatory

dynamics as observed in human vocal tract. In fact, the movement of the lips, even subtle, can

communicate relevant information to the human receiver. This is even more crucial for some

population such as hard-of-hearing people.

Missions

The goal of this work is to develop an accurate 3D lip model that can be integrated within a talking

head. A control model will also be developed. The lip model should be as accurate dynamically as

possible. When designing this model, the focus will be on the dynamics. For this reason, one can

start from a static 3D lip mesh, using a generic 3D lip model, and then we will use MRI images or 3D

scans to obtain more realistic shape of the lips. To take into account the dynamic aspect of the lip

deformation, we will use an articulograph (EMA) and motion capture technique to track sensors or

markers on the lips. The mesh will be adapted to this data. To control the lips, we will consider

allowing a skeletal animation to be controlled by the EMA sensors or motion capture markers, using

inverse kinematic technique, widely used in 3D modeling. In line with conventional skeletal animation,

an articulated armature rigged inside the mesh is mapped to vertex groups on the lip mesh by a

weight map that can be defined automatically from the envelope of the armature's shape and

manually adjusted if required, where manipulating the armature's components deforms the

surrounding mesh accordingly. The main challenge is to find the best topology of the sensors or

markers on the lips, to be able to better capture accurately its dynamics. The main outcome is to

accurately model and animate the lips based on articulatory data. It is very important to have

readable lips in that can be lip-read by hard-of-hearing people.

PhD Title: Birdsong Forensics for Species Identification and Separation

Studentship: Full Scholarship, including fees (EU/Non EU) plus annual stipend of €16,000.

Start Date: Sept 2nd 2013 

PhD Supervisor: Dr. Naomi Harte, Sigmedia Group, Electronic & Electrical Engineering, Trinity College Dublin, Ireland

Collaborator: Dr. Nicola Marples, Zoology, Trinity College Dublin, Ireland.

Background:

The analysis of birdsong has increased in the speech processing community in the past 5 years. Much of the reported research has concentrated on the identification of bird species from their songs or calls. Smartphone apps have been developed that claim to automatically identify a bird species from a live recording taken by the user. A lesser reported topic is the analysis of birdsongs from subspecies of the

same bird. Among experts, bird song is considered a particularly effective way of comparing birds at species level. Differences in song may help uncover cryptic species. In many species, such as those living in the high canopy, catching the birds in order to obtain morphological (e.g. weight, bill length, wing length etc.) and genetic data may be time consuming and expensive. Identifying potentially interesting populations by the detection of song differences, allows any such effort to be better targeted.

Birdsong presents many unique challenges as a signal. The use of signal processing and machine learning techniques for birdsong analysis is at a very early stage within the ornithological research community. This PhD project seeks to lead the way in defining the state of the art for forensic birdsong analysis. Comparing birdsongs will push out the boundaries of feature analysis and classification techniques in signal processing. The research will develop new algorithms to systematically quantify levels of similarity in birdsong, transforming the comparison of birdsong in the natural sciences arena. The results will be of importance internationally for the study, monitoring, and conservation of bird populations.

Requirements:

The ideal candidate for this position will:

 Have a primary degree (first class honours) in Electronic Engineering, Electronic and Computer Engineering or a closely related discipline.

 Possess strong written and oral communication skills in English.

 Have a strong background and interest in digital signal processing (DSP)

 Be mathematically minded, and be curious about nature.

Experience in Matlab is a distinct advantage.

Application:

Interested candidates should send an email to Dr. Naomi Harte at nharte@tcd.ie. The email

MUST include the following:

 Candidate CV (max 2 pages)

 A short statement of motivation (half page)

 Scanned academic transcripts

 Name and contact details for TWO academic referees

Incomplete applications may not be considered.
